Construction machine and operation state management system for the same

A construction machine comprising:

• a cumulative value storage device configured to store a cumulative value in which an amount of operation of the construction machine is accumulated and have an adjustment function to the stored cumulative value, the cumulative value storage device comprising a memory;
• a user input device for adjusting the cumulative value by rewriting the cumulative value stored in the cumulative value storage device at a present moment;
• and
• a communication terminal configured to communicate with a management apparatus outside the construction machine, wherein
• when the cumulative value storage device obtains a limitation request instruction to limit the adjustment function to the cumulative value that is performed using the user input device from the management apparatus, the cumulative value storage device turns off the adjustment function to the cumulative value.
